When Shawnece multiplies both sides of the equation x7 − 4 = −6 by 7, she is applying the concept of the inverse operation. The inverse operation of subtraction is addition. By multiplying both sides by 7, she is essentially undoing the subtraction of 4 from the left side of the equation. This allows her to isolate the variable x on one side of the equation, which is the goal of solving for x.
